B., WebRational minimax approximation of real functions on real intervals is an established topic, but when it comes to complex functions or domains, there appear to be no algorithms currently in use. Such a method is introduced here, the {\em AAA-Lawson algorithm,} available in Chebfun. The new algorithm solves a wide range of problems on arbitrary …
